Question

When i call

void fileOpen(const char*
 fname_){file_.Open(fname_,ios::in|ios::out|ios::ate|ios::binary);};

Function like
tempobj->fileOpen(“LastID.dat”);

It gives me the error

Error   23  error C2039: 'Open' : is not a member of 'std::basic_fstream<_Elem,_Traits>'

How do i resolve this. This is the class I have this function. It is template class

#ifndef FileHandlerh_h
#define FileHandlerh_h
#include <iostream>
#include <cstdlib>
#include <fstream>

using namespace std;
template <class T>
class FileHandler
{
    private:
        fstream file_;


    public:
        FileHandler(){};

        FileHandler(const char* fname_){fileOpen(fname_);};

        void fileOpen(const char* fname_){file_.Open(fname_,ios::in|ios::out|ios::ate|ios::binary);};

        void fileWrite(T);
        void fileSeekWrite(T,int);
        T fileRead(int);
        int getNoOfRecords();

        ~FileHandler(){file_.close();};

};

Help me with this…!!

C++ is case sensitive. You need to use open() instead of Open().
